Sprinkle Treatment of Bituminous Concrete for Improved Skid Resistance. (September, 1993)

摘要

The purpose of the report is the evaluation of Sprinkle Treatment of asphalt surface as compared to conventional treatment, ID-2 Wearing Course. Sprinkle treatment is intended to provide high frictional characteristics using a minimal amount of high quality aggregate. The evaluation is based on a 5 year collection of data as performed on two sections each of pavements (Sprinkle treated as compared to Control sections of conventional ID-2 wearing course) by the Pennsylvania Department of Transportation. The most significant results were in cost and skid resistance. The cost of sprinkle treatment increased 16% over the conventional. Sprinkle treated demonstrated superior skid resistance to the control sections. It is concluded that the sprinkle treatment is not a cost-effective alternative, at this time, because of the current supply of approved reasonably priced quality aggregate in Pennsylvania.
